What the law requires
The Older Workers Benefit Protection Act (1990) amends the Age Discrimination in Employment Act to govern how employers may obtain a valid waiver of ADEA claims from employees aged 40 or older. For a waiver to be enforceable, the employer must meet specific procedural requirements — any failure can void the release entirely.
In a group layoff, the employer must provide a decisional unit disclosure: a written list of the job titles and ages of all employees in the affected group, both those selected for termination and those not selected. This document must be provided at the time the severance agreement is presented.
Employees must have at least 45 days to consider the agreement in a group layoff (21 days for individual terminations). After signing, there is a mandatory 7-day revocation period during which the employee may rescind. The earliest the agreement can become effective is 52 days from disclosure (45 + 7).
The waiver must be in writing, reference the ADEA specifically, not waive future claims, and be supported by consideration beyond what the employee is already entitled to. Employers cannot simply add OWBPA language to an existing agreement — the procedural requirements must be met independently.
